# Watchtower Spatial Research third-party notices Selected GTFS-Realtime decoding and satellite-pass calculations are adapted from God's Eye View by Bilawal Sidhu, commit e2274bbf0ceaeb2e14f8a59d63e77000553c6816, under the MIT source-code licence. The full notice is retained as GEV-LICENSE.txt. https://github.com/bilawalsidhu/gods-eye-view No TeleGeography, Bhote Koshi imagery/coordinates, third-party model collections or other bundled noncommercial datasets are included. Upstream source data and images retain their individually displayed terms and attribution. Build/runtime component notices are copied from their pinned packages during the build: satellite.js6.0.1 (MIT), pbf4.0.1 (BSD-3-Clause), fflate0.8.2 (MIT), Pannellum2.5.6 (MIT), @xmldom/xmldom0.9.12 (MIT, private XML import worker). esbuild is a local build tool only. Watchtower adds source-age/identity gates, bounded selected-object processing, account/replay isolation, source attribution, private import/scene handling and new application integration. Pass calculations use an assumed sea-level observer; numerical refinement does not establish corresponding real-world accuracy. ## God’s Eye View MIT License Copyright (c) 2026 Bilawal Sidhu Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.

The datasets bundled under src/data/local_data/, and all data fetched from third-party providers at runtime, are owned by their respective sources and are NOT licensed under MIT. They are included/visualized for convenience and remain subject to their own licenses and terms. Notably: - TeleGeography Submarine Cable Map (src/data/local_data/ telegeography_submarine_cables/): CC BY-NC-SA 3.0 — NonCommercial + ShareAlike. NOT for commercial use. If you use this project commercially, remove these files or obtain a commercial license from TeleGeography. - Datacenters and Dams (OpenStreetMap / Open Infrastructure Map extracts): Open Database License (ODbL) 1.0 — attribution + share-alike on the data. - NASA FIRMS active-fire snapshot: CC0 / U.S. public domain (citation requested). - Bhote Koshi event imagery and derived river centerline (public/events/bhote-koshi-2026/ and the coordinate dataset in src/data/bhoteKoshiFloodPath.js): Vantor / GeoPera, CC BY-NC 4.0. NOT for commercial use without separate permission. Source-linked witness posts retain their owners' terms; no witness clips are bundled. See the folder README for attribution and modification notices. The derived coordinates remain third-party data even though they are embedded in a JavaScript source file; the MIT grant does not cover that dataset. Live sources (Google Maps, OpenSky, adsb.lol, AISStream, CelesTrak, USGS, OSM Overpass, City of Austin, GBFS) are fetched at runtime under each provider's terms; some (e.g. Google Maps, OpenSky) restrict commercial use and require you to supply your own credentials. In short: the MIT grant does not extend to any third-party data. See DATA_SOURCES.md for the full per-source license + attribution summary, and remove any dataset whose terms don't fit your use. The 3D models under public/models/ are also third-party works and are NOT licensed under MIT. They remain under their individual licenses. See public/models/README.md for the author, source, license, modification notice, and attribution covering each model file. ## satellite.js MIT License Copyright (C) 2013 Shashwat Kandadai, UCSC Jack Baskin School of Engineering Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the "Software"), to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software.
